Thermes de Cluny

The Thermes de Cluny are the ruins of Gallo-Roman thermal baths in the heart of Paris' 5th arrondissement, built at the turn of the 1st or 2nd century AD. Covering approximately 6,000 square metres, they were Lutetia's largest public baths. The frigidarium, with vaults rising over 14 metres high, is among the best-preserved Roman structures in northern France. The walls feature opus vittatum mixtum technique with alternating layers of limestone and brick. Consoles are carved as ships' prows, linking the baths to the guild of boatmen. Destroyed by barbarian raids in the late 3rd century, the ruins are now part of the Musee de Cluny.
